5.3.2 Header

The header of the parameter file contains information about the file format
and contents.
The description array can be used to specify the goal
of the simulation, special model characteristics, or important parameter
changes compared to a previous or standard model.
The history array may contain the predecessor of the parameter file
to simplify a tracing of parameter changes.

which indicates that the file is in UIO form and Fortran ``formatted'' (ASCII).
The specification of the conversion type (``convert=ieee_4'') is
more relevant for unformatted files.
These terms should not be changed.
But it can be of interest to append e.g. the date of the last
modification (e.g. ``date='01.01.2002''').

character file_id:
The file identification string

character file_id f=A80 b=80 n='File identification'
rhd-parameter

indicates the intended use of the file as parameter file for the RHD code CO5BOLD.
Do not edit!

character description:
The header of the file can (should) contain a short description
of the simulation, as in e.g.

This entry is optional (it can be omitted completely) but it is
recommended to put at least some relevant keywords into this array.
If you change the number of lines (between 1 and 20) you have to
adjust the size specification (``d=(1:4)'' in the example above).

character history:
The file history has a similar purpose as the previous entry.
It can be used to keep information about the ``parent'' parameter file, as in

character history d=(1:2) f=A80 p=1 b=80 n='File history'
